Default Bleeding Brakes '81

The shop manual says to bleed left rear inner then outer, then right inner then outer, then left front, then right front. That seems backwards.
Are they talking as if looking at the car from the front, facing the car?
I always thought it was farthest from the master cylinder to closest?

Furthest to closest. I bleed mine all twice, so it really doesn't matter. Getting all the air out is the goal. Tap the calipers with a hammer to dislodge any bubbles.

Inner first, then outer is important or you spend a lot of time and fluid pulling tiny bubbles past the inner on the way to the outer. Do the inner first and get those out of the way or or it takes all day.

Left or right first isn't nearly as critical in my opinion. The left first is just to save time and fluid as any bubble in the front or rear distribution line will have a shorter travel distance to remove it. Less time, less fluid.

Not rocket science but we seem to spend soo much time and frustration desperately wrestling with bleeding C3 brakes that we sometimes overthink it.

Yup. I have an old shop manual that incorrectly states the same thing. I always figured that on the day that page went to print for publication, a doobie was involved.
